Change Authorization ASP.NET MVC 5 redirect page and return to returnUrl

I created an ActionResult Access denied controller an error box is generated whenever the user does not have permission, and I have also created the UserPermission class that I will use instead of Authorize > .

My problem is that I can not use the returnUrl, it redirects to the login page, but by logging in, it returns to Home, Index .

Or if you have a way to just create the error box within Authorize itself .

The class UserPermission :

using System.Linq;
using System.Web.Mvc;
using System.Web.Routing;

namespace PortalDeRelacionamentoProject.Util
{
    public class UsuarioPermissao : AuthorizeAttribute
    {
        protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
        {
            if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
            {
                // The user is not authenticated
                base.HandleUnauthorizedRequest(filterContext);
            }
            else if (!this.Roles.Split(',').Any(filterContext.HttpContext.User.IsInRole))
            {
                // The user is not in any of the listed roles => 
                // show the unauthorized view
                filterContext.Result = new RedirectToRouteResult(
                    new RouteValueDictionary(
                        new { Controller = "Account", action = "AcessoNegado", area = "" }));
            }
            else
            {
                base.HandleUnauthorizedRequest(filterContext);
            }
        }
    }
}

The Account controller is ActionResult AccessNegado

 public ActionResult AcessoNegado(string returnUrl)
        {
            ViewBag.ReturnUrl = returnUrl;
            TempData["AlertaUsuario"] = new Alerta()
            {
                Mensagem = "Seu usuário não tem permissão para realizar essa operação, entre em contato com o suporte.",
                EhFechavel = true,
                Tipo = "alert-danger",
                Titulo = "Erro"
            };
            return RedirectToAction("Login", new { ReturnUrl = returnUrl});
        }
